Breathe Easier+ to improve fitness in non-small cell lung cancer survivors and their partners

This non-randomized, single group study will test a 12-week, behavioral intervention for physical activity and stress management for survivors of non-small cell lung cancer (NSCLC) and a partner (family member or friend). The goals of this intervention, Breathe Easier+ (BE+), are to increase overall physical activity and overall fitness and to reduce symptoms (fatigue, breathlessness, sleep, and stress).

The aim of this study is to evaluate the enrollment, retention, adherence, participation, and acceptability of the 12-week BE+ among NSCLC survivors and their partners. The study also aims to:

1. Explore preliminary intervention effects of BE+ on increasing physical activity and overall fitness (measured by 7-day Fitbit wear, step-in-place test, chair sit-and-stand, arm curl test, and balance test) from baseline to post-intervention among NSCLC survivors and their partners. 2. Explore preliminary effects of BE+ for improvement in stress response, symptom burden (fatigue, dyspnea), sleep, and HRQL from baseline to post-intervention among NSCLC survivors and their partners.

Participants will receive education, social support, coaching, a guided walking program, supervised resistance training (RT), and meditations delivered via digital technology (tablet, smartphone, and Fitbit).
